Good except you need Bogdan and Pegh. To accommodate that change, swap Piotr to Bogdan, and Jalil to Pegh.

If you want to survive elo you need Bogdan for stop ability, plus its an awesome first turn drop for any scenario. And Pegh is your DR card which works perfectly for any poison lifegain deck.

The only thing i can think of is Pegh for Jalil, then Piotr to Grudg/Bogdan (preferably Bogdan, but people sometimes use Grudg)

This deck seems like it's going to get crushed when against SOB. Its damage, even with abilities, only reaches 29, or 34 including the life gap (when against sob). So, 29 divided by 8 = which is roughly 4 damage per card. Same with 34. That means you'll have to win quite a few rounds to do some damage. DR + Sob? Not sure this would survive

Piotr for Bogdan or Grudj

and Jalil for Pegh

Piotr for Wolfgang! Wolfgang is really underrated and amazing card. (Unless you can afford to splash Uranus)

Freeks can be quite good in ELO, I've gotten to 1400 with them but sadly not top 100
